数控机床伺服系统高精度位置检测研究与实现

Research on the high-precision rotor position detection of the machine tools servo system

提出了一种应用TMS320LF2407 DSP实现数控机床永磁交流伺服系统电机转子磁极位置的检 测方法,该方法充分利用了DSP片内资源,在不增加编码器分辨率的基础上减小了量化误差,提高转子位置检测精度,降低了系统成本。实验结果证明了这种检测方法的精确性和实用性。

In this paper, a new way of PMSM's rotor position detection based on DSP is presented.This method makes full use of the resource of DSP and the measurement accuracy isgreatly improved with low-resolution encoder. The experiment result proves the methodaccurate and practical.
